[Nanamoto] Hagemashi? Brother (Gekkan Web Otoko no Ko-llection! S Vol. 72) [mysterymeat3]

Haruka, a doting little brother who dresses the part of an adorable schoolgirl, decides his studious, glasses-wearing older brother needs far more than a study break after a failed college exam leaves him wound tight. Slipping beneath the desk as test dates loom on the calendar, Haruka works his flustered sibling past the protests that brothers shouldn't do this, then soothes him with surprising tenderness before taking the lead on a creaking bed. A sweet-and-steamy sibling story where the biggest distraction turns out to be the best medicine.
